How can I solve these errors in AndroidManifest.xml?

Question

I have changed something manually in my android manifest in one of the activities and now many lines of my manifest are in red

I have errors like "Uri is not registered", "Attribute is not allowed here", etc.

This is the complete AndroidManifest.xml

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.dogsgame"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="30" />

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

<supports-gl-texture android:name="GL_OES_compressed_ETC1_RGB8_texture" />
<supports-gl-texture android:name="GL_OES_compressed_paletted_texture" />

<application

    <activity
        android:name="com.example.dogsgame.backdog"
        android:theme="@style/Theme.AppCompat.NoActionBar" />
    <activity
        android:name="com.example.dogsgame.dogoutside"
        android:theme="@style/Theme.AppCompat.NoActionBar" />
    <activity
        android:name="com.example.dogsgame.dog"
        android:theme="@style/Theme.AppCompat.NoActionBar" />
    <activity
        android:name="com.example.dogsgame.choosedogs"
        android:theme="@style/Theme.AppCompat.NoActionBar" />
    <activity
        android:name="com.example.dogsgame.secondactivity"
        android:theme="@style/Theme.AppCompat.NoActionBar" />
    <activity
        android:name="com.example.dogsgame.MainActivity"
        android:theme="@style/Theme.AppCompat.NoActionBar" />

    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</application>

Answer 1

you closed the MainActivity without the intent-filter

this is the solution

<activity
    android:name="com.example.dogsgame.MainActivity"
    android:theme="@style/Theme.AppCompat.NoActionBar" >

<intent-filter>
    <action android:name="android.intent.action.MAIN" />

    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
